SwitchExplanation
Formula: BTU = Kilocalories × 3.965667. Why: calories, kilocalories, and BTU each use fixed joule equivalents, so the route moves through joules and preserves one deterministic factor.
Kilocalories (kcal): an energy unit equal to 1,000 calories, commonly used in nutrition and food energy contexts.
BTU (BTU): a thermal energy unit with a fixed joule equivalent, common in HVAC, heating, and thermal-system references.
This route is useful when translating thermal and nutritional energy values across calories, kilocalories, BTU, and joule-based references without mixing the underlying definitions.
This conversion is purely multiplicative because both units reduce through joules using fixed energy definitions with no offset.
